As for how to keep the community active, we usually share one or two valuable topics in the group every day for the group friends to share actively. The rest of the active atmosphere is left to the group activities of community management tools, such as weather forecast, news broadcast, horoscope, lunar calendar, picture search, story and joke, health knowledge, Duke of Zhou, recipes and today's oil price. As long as the group members ask these questions, the community management tools will automatically reply to the relevant questions, making the community a valuable interactive place, and then members will naturally be more willing to come to the community to interact.
